The phase of mitosis in which the sister chromatids separate from each other
A
prophase
B
metaphase
C
anaphase
D
telophase
Explanation: 

Detailed explanation-1: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin-which linked the sister chromatids together during prophase-causes this separation to occur.

Detailed explanation-2: -There are 46 individual chromosomes in each cell. Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate.

Detailed explanation-3: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.

Detailed explanation-4: -During anaphase, the sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. Anaphase ensures that each daughter cell receives an identical set of chromosomes.

Detailed explanation-5: -Anaphase II is the stage when sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell. The separation and the movement is due to the shortening of the kinetochore microtubules.
